We designed and implemented a photoacoustic (PA) sensor for H 2 S detection in SF 6
background gas based on a multi-pass differential photoacoustic cell (MDPC) and a near-…

As a gold standard technique, enzyme-linked immunosorbent assay (ELISA) organically
combines immunoreactions between antigens and antibodies with enzyme catalysis. The use of …

A high-precision photoacoustic (PA) gas analyzer for fast dynamic measurement of ambient
nitrogen dioxide (NO 2 ) was developed. The PA analyzer used a differential PA cell …

A high-sensitivity fiber-optic Fabry-Perot (FP) photoacoustic gas detection system with properties
of anti-electromagnetic interference and intrinsically safe was presented for quantitative …

This work aims to develop a novel multimode (photothermal/colorimetric/fluorescent)
nanozyme-linked immunosorbent assay (NLISA) based on the in situ generation of Prussian blue …

A method to determine the focal length of a thermal lens and pumping laser beam waist in
the gain medium in laser-diode-pumped solid-state lasers is presented. This method, using …

We designed and manufactured a set of high-sensitivity photoacoustic (PA) gas detector
based on differential multi-pass cell (DMPC) with a chamber volume of only 162 mL, which …

To realize all-optical passive detection of CH 4 in narrow spaces and harsh environments, a
compact cantilever-enhanced fiber-optic photoacoustic sensor (CEFPS) resistant to …

To achieve high sensitivity detection of dual-component greenhouse gases carbon dioxide
and methane simultaneously, a multimechanism synergistic enhanced all-optical …

A miniature fiber-optic Fabry–Perot (FP) accelerometer based on phase demodulation is
demonstrated for improving sensitivity. The accelerometer is composed of a 11.5 mm diameter …
